COD AND COLOR REMOVAL FROM WASTEWATERS: OPTIMIZATION OF FENTON PROCESS
Abstract :
In this study, COD and color removal from wastewaters by Fenton’s oxidation were investigated. In the study the response variables of Y1 and Y2 were selected as COD removal rate (%) and color removal rate(%), and efficacy variables of A, B, anc C were selected as H2O2 concentration (mmol/L), reaction time (h) and H2O2/Fe^2+. The experimental design was used as a two-level factorial design. In the corner points 2³ = 8, in the center points 3 and a total of 3.(8+3)=33 experiments were conducted. Effect of H2O2 concentration (mmol/L), reaction time (h) and H2O2/Fe^2+ molar ratio on COD removal rate and color removal rate were investigated. The optimum conditions for maximum COD removal rate and color removal rate were at H2O2 concentration 8 mmol/L, reaction time 3 h and H2O2/Fe^2+ molar ratio 2.6. At optimum conditions 82% COD removal rate and 93% color removal rate were achieved.
